Maps do not work correctly in custom dimensions

Short description:

Maps do not behave correctly when teleporting between custom dimensions

Long version:

When creating a map (locator) in a custom dimension, the player locator symbol behaves inconsistent. It may turn completely black or disappear entirely

Steps to reproduce:

1. Create a world using the custom dimension script api

2. Go to the custom dimension and create a locator map

3. Teleport out of the dimension to the overworld or another custom dimension.

Observations:

• the locator icon may appear completely black

• When reloading the world, it completely disappears.

Expected:

• The icons works as if the player is in the nether or end (does not disappear or turn completely black)

I have included a sample world with the same dimensions/scripts as in the Minecraft creator YouTube channel
